Q1. The magnification produced by a spherical mirror is given by the formula m = -v/u. A concave mirror produces an image at v = -30 cm for an object at u = -10 cm. The magnification is:
Answer: -3
Explanation: Using the magnification formula m = −v/u, with v = −30 cm and u = −10 cm, gives m = −(−30)/(−10) = −3. The negative value confirms the image is real and inverted, which is characteristic of a concave mirror when the object is beyond the focal point.
